dszeto2 opened a new issue #16471: CMake build with MKL_USE_ILP64 throws type mismatch
URL: https://github.com/apache/incubator-mxnet/issues/16471
 
 
   When setting `MKL_USE_ILP64` to `On` in the CMake build, the build fails:
   ```

   The rest of my CMake build command is here:
   ```
   cmake \
   -DUSE_CUDA=Off \
   -DUSE_CUDNN=Off \
   -DUSE_LAPACK=On \
   -DUSE_F16C=Off \
   -DBLAS=MKL \
   -DUSE_OPENCV=Off \
   -DUSE_PROFILER=On \
   -DUSE_MKLDNN=Off \
   -DUSE_OPENMP=On \
   -DBUILD_CPP_EXAMPLES=Off \
   -DMKL_USE_SINGLE_DYNAMIC_LIBRARY=Off \
   -DMKL_USE_STATIC_LIBS=Off \
   -DCMAKE_SHARED_LINKER_FLAGS="-lrt" \
   -DCMAKE_SKIP_BUILD_RPATH=On \
   -DCMAKE_BUILD_WITH_INSTALL_RPATH=On \
   -DCMAKE_INSTALL_RPATH="\$ORIGIN" \
   -DINTEL_ROOT=/opt/intel \
   -DMKL_ROOT=/opt/intel/mkl \
   -DMKL_USE_ILP64=On \
   -DMKL_USE_CLUSTER=Off \
   -DUSE_MKL_IF_AVAILABLE=On \
   -DINTEL_RTL_ROOT=/opt/intel/lib/intel64_lin \
   -DCMAKE_BUILD_TYPE=Release \
   ..
   ```
   I'm using `gcc 4.8.2` on CentOS-6 from commit `f52ddfd880ad9d0e5a9d26eb41aabdd96fa4ac65`. Setting `MKL_USE_ILP64` to `Off` gets mxnet to build and successfully link against libmkl_intel_lp64.so, which is expected. Any help would be appreciated.
